TYPE-WRITER-ACTUATING NIECHANISNI.

SPECIFICATION forming part of vLetters Patent No. 765,799, .dated July26, 1904. Application led October 27, 1903. Serial No. 178,686. (Nomodel.)

To all whom. t panty-concern:

.Be it known that I, vWILLIAM Gr. SPIEGEL,

a citizen of the United States of America, and

a resident of New York city, county and State of New York, have inventedcertain new and useful Improvements in Type-lVriter-Actuating Mechanism,of which the following is a speciiication.

My invention relates to auxiliary electric apparatus for operating typewriting machines, so as to mainly relieve the fingers of the operator ofthe labor of working the keys,

the apparatus being particularly designed for ready application to andremoval from machines in use, so as to enable the employment of it ornot at the will of the operator, as

hereinafter described, reference being madeto the accompanying'drawings, in which- Figure l is a vertical sectional elevation of 2o atype-writing machine of common form and my improved auxiliaryelectric-power apparatus applied thereto suitably for operating thekey-levers, whether consisting of magnetic or non-magnetic material, thesection l being in the plane of one of the key-levers. Fig. 2 is adetail in plan view showing a plan for the disposition 0i' theelectromagnets used for operating the key-levers in relation theret0whereby the magnets oi' suitable size may i the key-levers. Fig. 3 is adetail in vertical section, showing the application of theelectromagnets so as to utilize the key-levers as the armatures of themagnets when the said levers consist of magnetic material. Fig. 4 is adetail in vertical` transverse section of the machine on a reducedscale, showing the be disposed in the limited space occupied byl use, inwhich A represents the bed-piece; a,

the posts; the top frame; c, the type-levers pivoted on said frame atCZ; e, connecting-rods; f, key-levers to which said rods e areconnected; g, pivots ofthe key-levers, and L the keys for operating themachine in the usual manner.

In the application ci' my invention to such a machine or any of likecharacter I provide a hollow base, whereoil represents the front side;y', the back; j', the lateral sides, and 7c the bottom, adapted toreceive the lower edge of base A within its top, as shown at Z, withadjusting-screws m on which to seat said base A and by which to adjustit subsequently. In this base under the key-levers f I provide anelectromagnet n for each lever to operate Vit either directly when thelever is of metallic substance subject to the pull -oi' the magnets, asindicated in Fig. 3, or

through intermediate means, as an armature 0 and a hook-headed bar p, asin Fig. l, or any other equivalent contrivance where the key-levers maybe non-responsive to the pull of the magnets or where it may be desiredto adapt the connection alike for levers of either character. Thearmatures have a tubular T-head q and are strung on wire pivots fr,extending from side to side of the basechamber and supported in suitableports s, and the hook-bars p are pivoted at t to the free ends of thearmatures and extend above their respective key-levers and engage themby a hook-head u thereabove.

To dispose the magnets in the laterally-limited space occupied by thekey-levers and enable a magnet oi' suitable size to be appropriated toeach key-lever, I have in this instance arranged them in two series oftwo tiers each, as shown in Figs. l and 2, thus overlapping them andreducing the ranks within the space afforded. The magnets are mounted onthe bars c, traversing the chamber in the supporting-base and secured inany suitable way thereon.

In the application of the type-writing machine to the apparatus of myinvention the said machine is presentedv over the said appa-- atus' sothat the hook-heads will enter between the key-levers, and after theheads reach above the key-levers the machine is shifted laterally, asindicated in Fig. 4, so that the heads overhang the key-levers suitablyfor engaging and operating the levers. It will be noted, however, thatwhen the hookheads are not thus connected over the key-levers thearmatures will drop onto the polepieces oi' the magnets too low for suchlateral adjustment with the type-writing machine in the workingposition, as represented in Fig. 1. The adjusting-screws m, whichreceive and support the base A ot' the type-writing machine, aretherefore constructed in such long range that being first screwed downto a predetermined limit the key-levers will drop suficiently to allowthe hook-heads to be shifted over them even with the armatures restingon the pole-pieces, and when thus engaged the type-writing machine maybe restored to the proper position by the screws, and the screws arethus at the same time available for adjusting the armatures relativelyto the polepieces oi' the magnets.

In Fig. 3 the key-levers f may be supposed to consist of a metal bar,which may serve as the armature of the electromagnet, thus enabling thearmature appliances of F ig. 1 to be dispensed with in apparatus formachines having such key-levers. To operate these magnets and throughthem operate the key-levers with the advantage of only exercising theslight manual power required to close push-button contacts, I provide ona suitable keyboard 'w a bank of push-button contacts w and. y, locateddirectly over the keys L, with the buttons correspondingly markedrelatively to the keys, so that closing any one will complete theelectric circuit through the magnet connected with the correspondingkey-lever, and thus actuate the type-lever same as if the key L weremanually operated, the said keyboard being adapted for ready applicationand removal, according as it is desired to use the electric power ornot.

The contrivance herein represented for such application consists of thevertical end pieces and front piece 2 of the keyboard provided with aiange 3, adapted to rest on the upper l edge of the front part of theinclosing base for the magnets, so that the buttons register with thekeys i below, with a marginal extensions of said parts extending belowthe seat whereon said iange 3 rests, as shown in full lines at the frontand indicated by the dotted line along the left side to stay the saidboard in position.

In order that the push-button keyboard may be thus detachably appliedwithout interference with the circuit-wires and so as to avoid anytrouble in making and unmaking connections, the feed-wires 6, throughthe magnets to the button-springs 7, are each connected ,with aninsulated conducting-piece 8, suitably fixed on the upper edge of frontside f/ of the inclosing base, and on the under side of flange 3 of thekeyboard is a corresponding insulated conducting-piece 9, from which theparts 6' of said wires lead to the said button-springs, respectively,and the return-wires 10 of the push-buttons are connected to aconductingbar 11 on the lower edge ot' front 2 of the keyboard, underwhich is a conducting-bar 12, resting on front t' of the inclosing base,from which a return-wire 1-1 leads to the battery 15, so that merelyplacing the keyboard w in position connects the circuits and lifting itoliil disconnects them and allows the keyboard to be removed withoutinterference by wires.

What I claim as my invention is- 1. In electrictype-writing-machine-operating apparatus, the combination of a hollowbase adapted for reception and seating of the type-writing machine inoperative position in or over the upper portion of the chamber of saidbase, electromagnetic means in said chamber below the type-writingmachine when seated on said base, and in suitable relation to eachkey-lever respectively for operating it, a detachably-applied keyboardwith suitable push-button contacts located over the type-writing-machinekeys and registering with them respectively, and a source ofmagnet-energizing force in circuit with the said magnetic means and thepush-button contacts respectively.
